如何更新母版页控件中的 updatePanel？
我有一个 Web 控件，我在其中放置了 updatePanel。该控件注册在母版页中。在这个 Master 的 contentPage 中，我有一个按钮，我想在 Web 控制中更新我的更新面板。好像就这么简单……对吧！？但这是行不通的。
这是我的沉默&代码：
母版页：
<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="SiteMaster1.master.cs" Inherits="KR.Obsession.UI.Web.Masters.SiteMaster1" %>
<%@ Register Src="~/UserControls/ShoppingCart.ascx" TagName="Cart" TagPrefix="uc" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
</head>
<body>
<form id="form1" runat="server">
<ajaxToolkit:ToolkitScriptManager EnablePageMethods="true" runat="server" ID="AjaxScrpMngr1"
EnablePartialRendering="true" EnableScriptGlobalization="true" EnableScriptLocalization="true" >
</ajaxToolkit:ToolkitScriptManager>
<asp:ContentPlaceHolder ID="content" runat="server">
</asp:ContentPlaceHolder>
</form>
</body>
</html>
Web 控件：
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ShoppingCart.ascx.cs" Inherits="KR.Obsession.UI.Web.UserControls.ShoppingCart" %>
<asp:UpdatePanel runat="server" ID="PanUpdateCart" UpdateMode="Conditional" >
<ContentTemplate>
<div class="UserControlCart">
<div class="CartImage">
<asp:HyperLink runat="server" ID="LnkCart" ImageUrl="~/Images/Cart.gif" Width="29" Height="27" />
</div>
<div class="CartContent">
<asp:Literal runat="server" ID="LtrCount" Text="У вас: <b>{0}</b> вещиц" />
<br />
<asp:Literal runat="server" ID="LtrTotal" Text="на сумму <b>{0}</b>" />
</div>
</div>
</ContentTemplate>
</asp:UpdatePanel>
和页面：
%@ Page Title="" Language="C#" MasterPageFile="~/Masters/SiteMaster1.Master" AutoEventWireup="true" CodeBehind="ShowItem.aspx.cs" Inherits="KR.Obsession.UI.Web.ShowItem" %>
<%@ MasterType VirtualPath="~/Masters/SiteMaster1.Master" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:LinkButton runat="server" ID="LnkBtnAddToCart" CssClass="AddToCart" Text="ДОБАВИТЬ В КОРЗИНКУ" Enabled="false" OnClick="btnAddToCart_Click" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="LnkBtnAddToCart" EventName="Clicked" />
</Triggers>
</asp:UpdatePanel>
</asp:Content>
在我的控件后面的代码中，我有：
using System;
using KR.Obsession.UI.Core;
namespace KR.Obsession.UI.Web.UserControls
{
public partial class ShoppingCart : SharedBaseControl
{
protected void Page_Load(object sender, EventArgs e)
{
PanUpdateCart_Load();
}
public void PanUpdateCart_Load()
{
if (this.Profile.ShoppingCart.Items.Count > 0)
{
LtrCount.Text = string.Format(LtrCount.Text, this.Profile.ShoppingCart.Items.Count.ToString());
LtrTotal.Text = string.Format(LtrTotal.Text, UiUtilities.FormatPrice(this.Profile.ShoppingCart.Total));
}
else
{
LtrCount.Text = string.Format(LtrCount.Text, 0);
LtrTotal.Text = string.Format(LtrTotal.Text, UiUtilities.FormatPrice(0));
}
}
}
}
我希望 Web 控件以异步方式单击页面按钮上的 PanUpdateCart_Load() 方法。这可能吗？
I have a web control, where I put an updatePanel. This control is registered in the master page. In the contentPage from this Master I have a button, that I want to cause an Update of my Update Panel in web control. It seems to be so simple... right!? But it won't work.
Here is my murkup & code:
The Master Page:
<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="SiteMaster1.master.cs" Inherits="KR.Obsession.UI.Web.Masters.SiteMaster1" %>
<%@ Register Src="~/UserControls/ShoppingCart.ascx" TagName="Cart" TagPrefix="uc" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
</head>
<body>
<form id="form1" runat="server">
<ajaxToolkit:ToolkitScriptManager EnablePageMethods="true" runat="server" ID="AjaxScrpMngr1"
EnablePartialRendering="true" EnableScriptGlobalization="true" EnableScriptLocalization="true" >
</ajaxToolkit:ToolkitScriptManager>
<asp:ContentPlaceHolder ID="content" runat="server">
</asp:ContentPlaceHolder>
</form>
</body>
</html>
The web control:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ShoppingCart.ascx.cs" Inherits="KR.Obsession.UI.Web.UserControls.ShoppingCart" %>
<asp:UpdatePanel runat="server" ID="PanUpdateCart" UpdateMode="Conditional" >
<ContentTemplate>
<div class="UserControlCart">
<div class="CartImage">
<asp:HyperLink runat="server" ID="LnkCart" ImageUrl="~/Images/Cart.gif" Width="29" Height="27" />
</div>
<div class="CartContent">
<asp:Literal runat="server" ID="LtrCount" Text="У вас: <b>{0}</b> вещиц" />
<br />
<asp:Literal runat="server" ID="LtrTotal" Text="на сумму <b>{0}</b>" />
</div>
</div>
</ContentTemplate>
</asp:UpdatePanel>
and the Page:
%@ Page Title="" Language="C#" MasterPageFile="~/Masters/SiteMaster1.Master" AutoEventWireup="true" CodeBehind="ShowItem.aspx.cs" Inherits="KR.Obsession.UI.Web.ShowItem" %>
<%@ MasterType VirtualPath="~/Masters/SiteMaster1.Master" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:LinkButton runat="server" ID="LnkBtnAddToCart" CssClass="AddToCart" Text="ДОБАВИТЬ В КОРЗИНКУ" Enabled="false" OnClick="btnAddToCart_Click" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="LnkBtnAddToCart" EventName="Clicked" />
</Triggers>
</asp:UpdatePanel>
</asp:Content>
In the code behind of my control I have:
using System;
using KR.Obsession.UI.Core;
namespace KR.Obsession.UI.Web.UserControls
{
public partial class ShoppingCart : SharedBaseControl
{
protected void Page_Load(object sender, EventArgs e)
{
PanUpdateCart_Load();
}
public void PanUpdateCart_Load()
{
if (this.Profile.ShoppingCart.Items.Count > 0)
{
LtrCount.Text = string.Format(LtrCount.Text, this.Profile.ShoppingCart.Items.Count.ToString());
LtrTotal.Text = string.Format(LtrTotal.Text, UiUtilities.FormatPrice(this.Profile.ShoppingCart.Total));
}
else
{
LtrCount.Text = string.Format(LtrCount.Text, 0);
LtrTotal.Text = string.Format(LtrTotal.Text, UiUtilities.FormatPrice(0));
}
}
}
}
I want the web control run PanUpdateCart_Load() method on Page's button click in async way. Is that possible?

我认为必须如此
，但我不确定这是否是导致问题的原因，但您可以检查一下。
I think has to be
but I'm not sure if that's what is causing the issue but you can check.
